Applied Acoustics, 1989
Abstract Four approaches to underwater sound propagation modelling are reviewed including rays, normal modes, Green's function integral, and parabolic equation. Specific programs are discussed. Particular reference is made to the problems in running models and the applicability in various regimes, especially deep-water environments.

Bistatic model of ocean scattering
IEEE Transactions on Antennas and Propagation, 1998An analytical closed-form model is derived for the average power echo received by a bistatic altimeter from an oceanic surface at a frequency high enough for the Kirchhoff scattering mechanism to be dominant over the Bragg resonance one. The asymmetric behavior of the sea waves is taken into account, modeling the surface height as a non-Gaussian ...

Publisher Summary This chapter describes various aspects of the modeling of ocean circulation. Modeling the ocean circulation is entering a new era due to two major technical developments. One of these developments is the satellite-borne altimeter, which can provide a nearly synoptic view of the sea-surface elevation of the World Ocean.

Modelling ice-shelf/ocean interaction
2023The effect of climate change on the mass balance of ice shelves and bottom water formation is investigated using a terrain-following three-dimensional numerical ocean model. The Regional Ocean Modeling System was modified to simulate the thermodynamic processes beneath ice shelves, including direct basal processes and frazil ice dynamics.

Applied Optics, 1997
Ocean color is determined by spectral variations in reflectance at the sea surface. In the analytic model presented here, reflectance at the sea surface is estimated with the quasi-single-scattering approximation that ignores transspectral processes. The analytic solutions we obtained are valid for a vertically homogeneous water column.

Ocean Circulation Models and Modeling
2013Abstract This chapter focuses on numerical models used to understand and predict large-scale circulation, such as the circulation comprising basin and global scales. It is organized according to two themes. The first addresses physical and numerical topics forming a foundation for ocean models.

Glacial Ocean Carbon Cycle Modeling
1994The Hamburg Oceanic Carbon Cycle Circulation Model as a global tracer model suited for glacial ocean studies is briefly described. Experimental strategies for paleoclimatic model experiments are outlined. In sensitivity experiments the effect of a hydrography shift due to a change in sea level on the marine carbon cycle is investigated.

Modeling Open-Ocean Deep Convection
1997Abstract : LONG-TERM GOALS. To understand the convective process in the ocean, develop numerical models to study it, and so improve the representation of convection in ocean circulation models. OBJECTIVES. To understand the relative importance of vertical mixing by convection and lateral advection by geostrophic eddies in setting the volume and ...
